Description

The present invention relates to a reset device for a steering column arm for motor vehicles.

Steering column levers are e.g. B. known as a turn signal switch, wiper switch or the like. These switches each have a switch lever, via which the switch is operated. For actuation, the switch is deflected from a neutral position into a switching position, it being known that the switch can have more than one switching position and, in particular with turn signal levers, the switching positions can be on both sides of the neutral position. The provision of such steering column levers from the locked switching position can be done either manually or automatically, for. B. by the reset triggered by the steering wheel by means of a reset device. In certain situations, a reset of the steering column stalk must be guaranteed automatically, for example, a turn signal reset must be ensured regardless of the position of the steering wheel. Steering column levers are therefore known from the prior art, in which the latching can be released automatically. The latching can also be released, for example, electromechanically.

From the DE102013215202A1 a turn signal switch for a vehicle and a method for resetting such a turn signal switch is known. For this purpose, the turn signal switch comprises an actuating lever and a magnetically actuated locking device. The actuating lever can be deflected from a zero position into at least one switching position. The locking device is designed to hold the operating lever in its deflected switching position and to release it. According to the invention, the actuating lever is mechanically independently kept purely magnetic in its deflected switching position.

From the EP1939039 A reset device for a switch of a motor vehicle is known, in particular a turn signal switch, with a pivotably mounted, latchable shift lever with a spring-loaded latching element which interacts with at least one switch position of a latching curve on the housing side, an electromechanical adjusting device canceling the latching of the shift lever in a computer-controlled manner, which includes Adjusting device at least one electromagnet, which is activated by computer control and acts on the magnetic locking curve or provided with a magnetic plate and releases the locking of the switching lever.

From the DE102006052108A1 a flashing safety system is known, a grid being made of a magnetizable metal instead of plastic as previously. After the blinking function has ended, the control from the control chip by means of a current flow causes a magnetic coil to pull back the grid made of magnetizable steel and thereby compress the compression spring. Two middle position springs are pre-tensioned and consist of spring wire. They cause each other to center the switched-on turn signal lever when it is switched off into the rest position.

A disadvantage of the prior art mentioned above is that the electromagnetic adjustment device acts on the entire locking curve and the locking can only be released by adjusting the locking curve. However, a lot of space is required to adjust the locking curve. Another disadvantage is that the actuator for releasing the latching of the turn signal lever is not arranged on the latching link side, whereby a more compact design of the turn signal lever is prevented.

Based on the above-mentioned prior art, the invention is therefore based on the object of specifying a resetting device for a steering column arm for motor vehicles, which reliably ensures that the latching can be released with little mechanical effort in a simple manner and enables a compact construction of the steering column lever.

The object is achieved according to the invention by the features of the independent claims. Advantageous embodiments of the invention are specified in the subclaims.

According to the invention, a reset device for a steering column arm for motor vehicles is thus specified, comprising a shift lever with a spring-loaded latching element, a guide link for guiding the spring-loaded latching element and for latching the shift lever with the spring-loaded latching element in at least one switching position, an actuating device, the actuating device being arranged on the guide linkage side , The actuating device is designed to release the latching of the spring-loaded latching element in the at least one switching position when actuated, characterized in that the guide link is immobile, the actuating device has a movable element, the actuating device is set up in such a way by means of the movable element on the spring-loaded Act locking element to release the locking of the spring-loaded locking element in the at least one switching position.

The basic idea of the present invention is therefore to lock a shift lever with a guide link by means of a movable element to solve. By using the movable element, a simple and safe resolution of the locking of the spring-loaded locking element of the shift lever with the guide link can be ensured.

In an advantageous embodiment of the invention, the actuating device comprises an electrical actuator with at least one electrical coil and at least one magnetic element arranged on the movable element. The resetting and thus releasing the locking of the shift lever can take place automatically by means of an electrical actuator. In contrast to mechanical shift lever resets, the shift lever can be reset independently of the position of the steering wheel, for example.

In a further advantageous embodiment of the invention, the movable element of the actuation device is biased by a spring and the actuator moves the movable element against the bias of the spring when the actuation device is actuated. This is advantageous because, depending on the version, the latching can be released either with energy expenditure or also without energy expenditure, which means that depending on the version, the latching function can be guaranteed in the event of a power failure or the latching is automatically released in the event of a power failure.

In an advantageous embodiment of the invention, the actuator is set up to generate a current flow through the at least one electrical coil when actuated, to repel the at least one magnetic element and to move the movable element against the bias of the spring. As a result, different reset scenarios can be provided for different energy expenditure strategies.

In a further advantageous embodiment of the invention, the actuator is set up to generate a current flow through the at least one electrical coil when actuated, to attract the at least one magnetic element and to move the movable element against the bias of the spring. This is advantageous since it can be used to provide different reset scenarios for different energy expenditure strategies.

In an advantageous embodiment of the invention, the guide link comprises at least one locking lug for each shift position of the shift lever. A simple latching of the spring-loaded latching element with the guide link can be achieved by latching lugs.

In a further advantageous embodiment of the invention, the actuating device is designed such that the at least one movable element forms a latching lug for each switching position of the switching lever. Depending on the required function of the shift lever, different locking positions can be switched by retracting one or more movable elements.

In an advantageous embodiment of the invention, the movable element is designed and arranged to be held by the bias of the spring in a position in which the movable element forms the at least one locking lug. This also means that the locking function is activated without energy expenditure and the locking function is still guaranteed in the event of a power failure.

In a further advantageous embodiment of the invention, the movable element is designed to be held by the bias of the spring in a position in which the movable element is held outside the guide link when the electrical actuator is not actuated and the spring-loaded latching element is freely along the guide link is feasible. This is advantageous because, for example, if the power supply fails, the locking function is deactivated and the shift lever is returned to the neutral position.

In an advantageous embodiment of the invention, the actuating device is set up to release the latching between the latching lug and the spring-loaded latching element when actuated.

In a further advantageous embodiment of the invention, the reset device has a plurality of actuating devices for a plurality of switching positions, in particular one actuating device per switching position. This is advantageous since the actuating devices can be designed differently for different switching positions.

In an advantageous embodiment of the invention, the resetting device has a common actuating device for the plurality of switching positions. The advantage here is that only a single compact unit has to be provided, for example as a standardized assembly, and this enables a simultaneous release of the latching of several switching positions.

In a further advantageous embodiment of the invention, the movable element is pivotally mounted, the pivotably mounted element having a receptacle for the spring-loaded latching element, the actuator is designed to cause at least partial pivoting of the pivotably mounted element and thereby to release a locking between the spring-loaded locking element located in the receptacle and the receptacle. The pivotable mounting of the movable element has the advantage that no jamming or jamming of the movable element can occur when the latching is released due to the rotating or pivoting movement, thereby ensuring that the reset device functions reliably.

In an advantageous embodiment of the invention, the magnetic element is a permanent magnet or a ferromagnetic element.

The invention is explained in more detail below with reference to the attached drawing using preferred embodiments. The features shown can represent an aspect of the invention both individually and in combination. Features of various exemplary embodiments can be transferred from one exemplary embodiment to another.

The 1a and 1b show a reset device 1 for a steering column arm according to a first preferred embodiment. The reset device 1 includes a management backdrop 7 that have multiple switch positions 5 for a gear lever 3 having. The gear lever 3 can from a neutral position 6 along the V-shaped guide curve 8th in a switch position 5 be transferred. In the first embodiment, the guide link 7 designed as a latching backdrop and has at least one latch 9 for every switching position 5 , The gear lever 3 has a spring-loaded locking element 4 which when switching the shift lever 3 from the neutral position 6 in the switch position 5 with the latch 9 the leadership backdrop 7 locked. The locking between the spring-loaded locking element 4 and the latch 5 can by an actuator 2 be solved. It is provided that each switching position 5 its own actuator 2 having. The actuator 2 also has a movable element 11 on. The movable element 11 serves to lock the spring-loaded locking element 4 and the latch 9 by moving the movable element 11 to solve. The movement of the movable element 11 is done by means of an electric actuator 12 generated. In 1 is shown that the actuator 12 a magnetic element 14 and an electrical coil 13 having. The magnetic element 14 is between the movable element 11 and the electrical coil 13 arranged. It is also between the magnetic element 14 and the electrical coil 13 a feather 10 arranged. The feather 10 serves the movable element 11 the actuator 2 pretension. The actuator 12 moves when the actuator is actuated 2 the movable element 11 against the bias of the spring 10 , The actuator 2 can be done in a very compact design by nesting magnetic element 14 , Feather 10 and electric coil 13 can be combined into a compact functional unit. It can also be provided in a further embodiment that the magnetic element 14 in the movable element 11 is injected.

The reset device also includes 2 a microcontroller unit 18 , Via control lines 15 controls the microcontroller unit 18 the actuator 2 and can thus be locked between the spring-loaded locking element 4 and the guide link 7 to solve. The control lines 15 are with the actuator 12 connected.

Unlocking the gear lever 3 is therefore computer-controlled by means of the electromechanical actuating device 2 , Depending on the situation, different scenarios are conceivable. For example, the locking of the spring-loaded locking element 4 and the leadership backdrop 7 through the microcontroller unit 18 after a certain period of time, if, for example, the turn signal has been forgotten after a turning process that has not taken place, in the neutral position again 6 to move. Can also by the microcontroller unit 18 release the lock depending on the driving maneuver, for example, when a turning process or a lane change has been completed. For example, a speed-dependent angle can also be set for releasing the latching, so that, for example, the latching is released earlier at higher speeds. Furthermore, it can also be provided that individual functions of the reset device 2 can be deactivated. For example, it can be provided that the detent of the shift lever 3 is deactivated in a highly automated driving mode because, for example, only one tap function of the gear lever 3 is needed.

A device that the shift lever 3 back to neutral 6 is not shown in the figures. However, any embodiments are conceivable here. For example, springs or magnets can be provided that the shift lever 3 back to neutral 6 along the guide curve 8th moved back.

The 1a shows the reset device 1 with the actuator 2 , in which the spring-loaded locking element 4 with the latch 9 the leadership backdrop 7 is locked. The locking function of the reset device 1 is thus activated. The activation of the locking function is brought about by the electrical coil 13 an electric current flows and the magnetic element 14 against the force of the spring 10 attracts. This will make the magnetic element 14 connected movable element 11 against the force of the spring 10 towards the electrical coil 13 dressed. The spring-loaded locking element 4 thus remains with the latch 9 the leadership backdrop 7 locked.

In 1b is the reset device 1 with the actuator 2 shown, in which the spring-loaded locking element 4 with the latch 9 the leadership backdrop 7 is not locked. The locking function of the reset device 1 is therefore deactivated. By interrupting the flow of current through the electrical coil 13 becomes the movable element 11 through the force of the spring 10 against the spring-loaded locking element 4 pressed. As a result, the locking between the spring-loaded locking element 4 and the latch 9 solved. The locking function of the reset device is without energy expenditure 1 thus deactivated. If the power supply fails, the spring-loaded locking element is automatically locked 4 with the leadership backdrop 7 due to the force of the spring 10 solved.

In the 2a and 2 B is a second embodiment of a reset device 1 shown for a pitman arm. The reset device 2 of the second exemplary embodiment comprises a guide link 7 that have multiple switch positions 5 for a gear lever 3 having. The gear lever 3 can from a neutral position 6 along the V-shaped guide curve 8th in a switch position 5 be transferred. In the second embodiment, too, the guide link 7 via at least one latch 9 for every switching position 5 ,

In the 2a and 2 B is shown that the spring 10 not like in the first embodiment between the movable element 11 and the electrical coil 13 is arranged, but the spring 10 is with the movable element 11 and an attachment point 9 connected. As a result, the latching function is reversed in comparison to the first exemplary embodiment, as a result of which no current flows through the electrical coil 13 the locking function between the spring-loaded locking element 4 and the leadership backdrop 7 remains activated. With current flowing through the electrical coil 13 the locking function is deactivated, the movable element 11 is against the force of the spring 10 against the spring-loaded locking element 4 pressed and released. The gear lever 3 can then be in the neutral position 6 to be led back.

In 2a of the second embodiment is the reset device 2 with the actuator 2 shown, in which the spring-loaded locking element 4 with the latch 9 is locked. The locking function is thus activated. Through the electrical coil 13 no electricity flows. The latching function remains activated without energy expenditure. In the event of a power failure, the locking between the spring-loaded locking element 4 and the latch 9 the leadership backdrop 7 unsolved.

In 2 B of the second embodiment is the reset device 1 shown with the locking function deactivated. Through the electrical coil 13 a current flows through which the movable element 11 against the force of the spring 10 in the direction of the spring-loaded locking element 4 is moved. The latching function is deactivated when energy is used. In the event of a power failure, the locking between the spring-loaded locking element 4 and the latch 9 the leadership backdrop 7 unsolved.

The 3a and 3b show a schematic representation of a third embodiment of a reset device 1 for a pitman arm. In the third embodiment, the movable element forms 11 even at least one latch 9 for every switching position 5 , Depending on the required function of the shift lever 3 can set different locking positions by retracting one or more movable elements 11 be switched. In the 3a and 3b is shown that the spring 10 between the movable element 11 and an attachment point 16 is arranged.

In 3a of the third embodiment is the reset device 1 shown with the latching function activated. Through the electrical coil 13 no electricity flows. The feather 10 pushes the movable element 11 in the V-shaped course of the guide curve 8th , causing the movable element 11 even at least one latch 9 along the guide curve 8th forms. The locking function remains activated and the locking of the spring-loaded locking element without energy expenditure 4 with the through the movable locking element 11 formed latch 9 and the leadership backdrop 7 remains intact. If the power supply fails, the locking function is still guaranteed.

In 3b of the third embodiment is the reset device 1 shown with the locking function deactivated. Through the electrical coil 13 a current flows, causing the movable element 11 with the magnetic element 14 against the force of the spring 10 towards the electrical coil 13 is moved. This will cause the moving element 11 formed latch 9 along the guide curve 8th away. This disables the locking function and the gear lever 3 can along the guide curve 8th in the neutral position 6 be transferred.

The 4a and 4b show a schematic representation of a fourth embodiment of a reset device 1 for a pitman arm. In the 4a and 4b is shown that the actuator 2 just a movable element 11 for all switching positions 5 has. Because only a feather 10 , an electrical coil 13 and a magnetic element 14 the actuator may be needed 2 be provided as a single compact unit, for example as a standardized assembly. Through the common movable element 11 for all switching positions 5 can lock several switching positions 5 be solved at the same time. There is also the compact design of the movable element 11 the possibility of linear guides to the movable element 11 to attach, so as to jam the actuator 2 to prevent.

In 4a of the fourth embodiment is the reset device 1 shown with the latching function activated. Through the electrical coil 13 no electricity flows. The movable element 11 will counteract the force of the spring 10 towards the leadership backdrop 7 pressed. By moving the movable element 11 towards the leadership backdrop 7 are along the guide curve 8th locking lugs 9 through the movable element 11 formed by the spring-loaded locking element 4 with the leadership backdrop 7 is locked. In this embodiment, the latching function remains activated without expenditure of energy. If the power supply fails, the locking function is therefore guaranteed.

In 4b of the fourth embodiment is the reset device 1 shown with the locking function deactivated. Through which the electrical coil 13 a current flows, causing the movable element 11 against the force of the spring 10 is attracted. By moving the movable element 11 are those through the movable element 11 formed latches 9 along the guide curve 8th removed and the spring-loaded locking element 4 can along the guide curve 8th in the neutral position 6 be transferred.

The 5a and 5b show a schematic representation of a fifth embodiment of a reset device 1 for a pitman arm. In the fifth embodiment of the invention, the movable element 11 pivoted. The pivoted element 11 has a recording 17 around the spring-loaded locking element 4 to hold securely in a locked position. The locking between the spring-loaded locking element is achieved by a rotating or swiveling movement 4 and recording 17 of the pivotally mounted element 11 solved. Through a pivoted element 11 ensures that the movable element 11 not jammed or caught. In the 5a and 5b is shown that on the pivotally mounted element 11 a feather 10 is appropriate. The feather 10 presses the pivoted element 11 in a position where the recording 17 of the pivotally mounted element 11 the spring-loaded locking element 4 holds in a locked position. On the pivotally mounted element 11 is also a magnetic element 14 attached, which by the electrical coil 13 can be attracted or repelled. The reset device also has in the fifth exemplary embodiment 1 for every switching position 5 its own actuator 2 on.

In 5a is the reset device 1 shown with the latching function activated. Through the electrical coil 13 no current flows, so that on the pivotally mounted element 11 attached spring 10 the pivoted element 11 in presses a position at which the recording 17 the spring-loaded locking element 4 holds securely in the locked position. The locking function of the reset device remains without energy expenditure 1 activated and the locking function is guaranteed in the event of a power failure.

In 5b is the reset device 1 shown with the locking function deactivated. Through the electrical coil 13 a current flows and thereby strikes the pivoted element 11 attached magnetic element 14 against the force of the spring 10 from. This results in an at least partial pivoting of the pivotally mounted element 11 causes and the locking between the recording 17 and the spring-loaded locking element 4 solved.
